Street vision could hold the clue to Sydney man's savage beating

Detectives investigating a brutal bashing that left a man in a coma for three weeks hope new CCTV footage could help them track down the attackers.

Vineshwar Pal, 29, has still not regained consciousness and remains in a coma in Westmead Hospital after being attacked in Parramatta, in Sydney’s west, on November 4.

Officers were first called to a Brown Street home about 5am, following reports of a fight. After speaking with several people at the scene police left but were called back to a nearby home about 8.20am after a passer-by found a man unconscious in the front yard.

Mr Pal was found in a critical condition and rushed to hospital.

Strike Force Ramox was formed to investigate the attack and believe a group of men may have set on Mr Pal and beaten him.

Detectives today made the decision to release CCTV footage of a man they believe could assist them with their inquiries.
